DISK PRINTING.

Application led July 14, 1920. Serial No. 396,048.

To all whom t may concern:

Be it known that I, FRANCIS J. BUnAsK, a citizen of the United States of America, residing at Toledo, Lucas County, O hio, have invented new and useful Disk Printing, of which the following is a specification. l

This invention relates to printing multiple view records.

This invention has utility 'when incorporated for print-ing motion picture disk records for definite register as to angular starting, and for providing identification data.

Referring to the drawings:

Fig. 1 is a plan View of a printing apparatus embodying features of the invention, the holder being removed and sensitive sheet not in position;

Fig. 2 is a section through the apparatus of Fig. 1, fully assembled, with sensitive sheet therein for printing; and

y Fig. 3 is a fragmentary detail of the transparent base with centering and angular guides and identification data carrying transparency.

A rinting frame 1 is shown as having 1nwardIly extending ledge 2 for carrying transparent base or glass 3, having let thereinto centrally thereof a member 4. coming flush with the upper or inner face of the glass 3. Rising from this member 4 is a centering guide or pin 5, while eccentric thereof 1s an angular positioning guide or pin 6. Holes in data carrying transparency 7 may re ister such transparency not only centrally, ut angularly in fixed position on the base 3.

In practice the data earring transprency is a quite thin element which may complete as to title, film number, or even extend into a brief synopsis of the series of motion picture views, although primarily the element shows manufacturer or dealer and such information as will assist in ready handlingtherethrough registering with t e pins 5, 6,

to brin the starting point 9 in a definite p0- sition or use in the projecting machine.

The trans arencies as now described are fully assemb ed, and the pins 5, 6, still project slightly upward therebeyond, so in placing a light sensitive sheet 12 thereon with similar holes as to the holes in the negative 8, there is centering and angular position lixing identical with the negative 8. As thus assembled in the dark, holder members 13, 14, pivotally connected by hin e 15, may be placed in backing position an yieldably maintain the sensitive sheet 12 against the transparencies, by the action of spring straps 16 coacting with clips 17 on the frame 1. The apparatus is now in condition for light exposure in bringing about simultaneous printing upon the sensitive sheet 12 of the views of the negative 8 as Well as the identiiication data of the second transparency 7, all in centered and fixed angular position as to the view starting point 9. Accordingly in the development of the sheet l2 into a disk record its starting point will register with the starting point for the projection a paratus as determined by pins correspon ing to the centering pin ,5, and angular position iixing pin.,6 of the printing apparatus. The

sensitived lside of t e sheet 12 should be toward the transparencies `for having the record view seriesin the proper direction of spiral sequence.

The identification data carrier transparency 7, for specific matter, may have opaque portion or portions 18, which in printing clear on the positive 12,'provide s ace for dating, supplemental description, le numbers, etc., as may be convenient.

Reinforcement at the driving region of the positive 12, may be cared for by a disk 19 on one side, or both sides, in the central y portion, and this supplemented by eyelets 20 for the centering pin and 21 for the angular positionin pin, which eyelets 20, 21, may in some dis sizes be suflicient without the diskor disks 19.-

What is claimed and it is desired to secure by Letters Patent is:

1. A printing apparatus including a trans arent base, a centering pin rising there rom, an angular position determining 4guide pin also rising therefrom, said pins.

providing means for assembly of a positive 'transparency and a light sensitive means thereon, and a holder for yieldably applying pressure to hold the pin assembled transparency and sensitive means firmly against the base for light ray printing on sai sensitive means.

2. A printing apparatus including a transparent base, a member set into said base to come flush therewith, a centerin pin and an eccentric pin carried by sai member as centering and angular position fixing means for registering disk news during rinting, and a holder for opposing said ase. p

3. A printing apparatus including a transparent base, a member set into said base to come flush therewith, a. centering in and an eccentric in carried by said mem r for centering and) angularly fixing the position of a positive transparency, said positive having a transparent blank 're lon into which ma be registered by sai pins an identification data transparency, and a holder for crowding a\ light sensitive sheet toward said transparencies inv register 4with said pins for simultaneous printing from said transparencies.

In witness whereof I aiiix my signature.

FRANCIS J. BULASK.
